A parallel plate capacitor is composed of two parallel metal conductor plates, separated by a dielectric material in the middle. When there is a certain potential difference between the two plates, there will be an electrostatic field distribution between the plates. There is a uniform electric field distribution in the part between the two plates. Due [...]

We know that a series of AC coupling capacitors in the series signal can provide DC bias and overcurrent protection, but this will also bring another problem to the link PDJ (Pattern-Dependent Jitter). The placement of AC coupling capacitors has just been solved, and now we have encountered the value selection problem! Obviously, the AC coupling [...]

The decoupling capacitors is a capacitor installed on the power supply terminal of the component in the circuit. This capacitor can provide a more stable power supply, and can also reduce the noise of the component coupled to the power supply terminal, and indirectly can reduce the influence of other components on the noise of the [...]

CBB large capacitor chip capacitors have the characteristics of large capacity, small size, and easy chipization. It is one of the most used components in today's mobile communication equipment, computer boards and home appliance remote controls. In order to meet the needs of the development of electronic equipment in the direction of miniaturization, large capacity, high [...]

Misunderstandings about capacitance 1. The larger the capacitance, the better: Generally speaking, the larger the capacitance, the better, but this is not absolute. Large-capacity capacitors are not easy to filter out high-frequency interference signals, and multiple small-capacity capacitors in parallel are more effective and more stable than a single large-capacity capacitor. In addition, this has a [...]
